Problems linking to calloc

Hi everyone,
I am running rtems-4.6.0pre5 on a motorola 5272. I am also going to run
Microwindows on top of rtems. I can get a clean build of Microwindows for
rtems, but if I try to build any demos, I get errors from the linker saying
that it can't find calloc, rtems_semaphore_obtain, and others. We do have
the code for these functions in the rtems tree, but they aren't getting
linked in for some reason.
Is there a library that needs to be linked in that we are missing?
Below is a clip from the build log:
<SNIP>
/opt/rtems-4.6/bin/m68k-rtems-gcc -I.
-I/microwindows/microwindows-0.90-rtems/src/include

and on and on and on......

Thanks for any help you might provide,
